Mate u r having a laugh surely..

a socket set from halfords for 4.99 and about 5 quids worth of studs and bolts from Ford.

Undo boost hoses
Remove water and oild feeds (ok u need spanners for this)
Undo exhaust
about 9 (7 if u have 2 missing) bolts for the manifold to head

take it off.. replace bolts and re fit.

If u take it to a garage IMHO 30 quid TOPS.

Its a 10 minute job
